GOG Aluminum Freak XL Inserts

The Freak System allows you to get more shots from every fill-up, no matter what marker you shoot. By bore-matching your paintballs, you waste less air propelling them down your barrel. This means you can turn your regulator pressure down, or your velocity screw out making your marker softer on paint and easier on air.

In the first example, shows a ball that is too big for the bore chosen. This means that your marker has to use more air to push it down the barrel. This also can cause broken paint due to the extra friction. In the second example, we can see that the bore is too big for the paintball, and air is wasted blowing by the ball itself. In the last example we can see that the ball fits perfectly, with just the slightest gap around it to minimize friction and maximize efficiency.
